JQ N L-L BRIQATING' nnvron To all 'whom z't'mayconcern.

Be it known that I, GEORGE'VV. JORDAN, a citizen of the United States of America, and resident of Steubenville, county of Jefferson, and State of Ohio, have invented certain new and useful lmprovements in Journal- Lubri-cating Devices, ofwhich the following is aspecification.

This invention relates eating mechanisms, and more specifically to apparatus for feeding greaseto the'necks of rolls. 1

The primary object of the invention is to provide a force feed mechanism for furnishing to roll bearings, or to the necks or journals of rolls, as the rolls of a rolling mill, a constant supply of the heavy grease required for effecting proper lubrication.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is a side elevation of the invention mounted upon a rolling mill housing;

Figure 2 is a view of the same, partly in elevation and partly in vertical section, taken at a point at a right angle to the viewpoint in Fig. 1; and I c Figure 3 is an enlarged horizontal sectional elevation of a portion of the gearing which includes one member of the clutch and the crank arm.

Referring to said drawings, 1 indicates the upper roll of a set of rollingmill rolls,

. and 2 a housing of such mill. Mounted upon the housing 2 are suitablesnpports, as the brackets 3 and 4, by which is carried an upf Application filed December 2 4, 1e23.; Serial no esauau broadly to lubri-' right casing-like container 5 for grease which is to be supplied to theadjacent neck 1" of said roll 1. Said container is prefcrably of inverted conical, or funnel, form and has a wide hopper-like mouth portion 6 at its upper end Journaled in suitable bearings within said container is a central vertical shaft 7 which carries a spiral blade 8 of screw propeller type, by means of which.

grease introduced within said container is impelled from the lower end of the latter, as through a laterally disposed spout 9 which overhangs said roll neck.

While the bearings for the shaft 7 may be otherwise arranged, it is preferred that a bearing-plate, as 10,be suitably disposed in or at the lower end of the container 5 and that a horizontal cross bar 11 be detachably mounted upon the hopper 6, Said bar carrying a bearin Secured on the upper end portion of the shaft 7, as by a set screw 13, is a sleeve- 14.-

which carries a bevelgear 15; and disposed which is journaled in suitable bearings 18 and=19 formed on or carriediby the housingcarried brackete or other suitable support. I The outer section of said shaft 17 has keyed wobblers 27 of alined rolls of a rolltrain. 0 g

Springs 28 and 29 interposed, respectively, between the sleeve block and fixed collars; 30 and 31 carried by said rod are designed .to relieve back-lash.

. g '12 for the upper endbf {h shaft. k

in operative driving relation to'said gear 1s as1m1largear orp nion 16 earned by the inner section of a l1or1zontal shaft'17 A suitable clutch mechanism whereby the sections of the shaft 17 may be operatively connected and disconnected is provided, the clutch 32 herein shown being of a common type in which the shiftable member is moved by means of a hand lever 33.

Disposed for rotation with the shaftis one or-more radial arms 34,herein shown as.

carried by the sleeve 14, and carried by said arms are blades or scrapers 35 designed to be rotated within the hopper 6, close to the hopper walls for stirring or agitating the grease in ,saidhopper to cause it to feed downward within the casing to a level at which it will becaught by the revolving spiral blade 8.

While I have herein disclosed by invention in what I consider to be its simplest practical-form, it will be manifest that various changes in the details of construction and arrangement may be resorted to without departing. from the spirit of the invention as defined in the appended claims.

What is claimed is y 1. The combination with a set of rolling mill rolls and housings therefor, of mechanism for supplying lubricating grease to the neck of thenpper-otsaid ,roglls,-sai'd mechaneck of the upper of said rolls, said mechanism being operative onlyduring operation of said rolls and comprising a"snpp0 rt mounted on the housings adjacent to said neck, a grease container mounted on said support and having a'delivery spout at its lower end, a screw propeller, inonnted-. for rotation within said container for conveying grease downward in saidvncontainer and for extruding the same through said spout upon said roll neck, and drive gearing interposed between the drive coupling for-said rolls and said propeller, saidgearing em- ;bodying aliified shafts, aclutchlzfor operati-Vely. connecting and disconnecting, said shafts, and an eccentric drive intermediate one. of saidgshaft's and-said drive coupling. e 2. The combination with; aset of rolling mill rolls and housings therefor, oii mechanism z'torsupplying lubricating grease to the IllSIH comprising a support mounted on the housings adjacent to saidneck, a grease container {mounted on said supp ort,: said container having ahopper-like mouth portion at its upper end a delivery spout at its lower end, asha-ft journaled centrally withsaid container, a propeller screw carried by said shaft within the body portion of ;said container,fior eggtruding grease through said spout upon said roll neck, blade-like agitators carried by. said-z-shaft .within the hopper 'pQrtionof :tlie container, drive gear- ;ingior said lsha fit, vand -:s hittable 'means wl 1 er,eby. said gea1inganayibe rendered either operatlveor lnopenative.
